[0001] The invention relates to the technical field of steel bar cutting, and in particular to an intelligent steel bar cutting device for construction with controllable cutting length. Background Art

[0002] Rebar, the full name of which is steel for reinforced concrete and prestressed reinforced concrete, is usually round in cross section, sometimes square with rounded corners.

[0030] Reference Figure 1-7 , an intelligent steel bar cutting device for construction with controllable cutting length, comprising a workbench 1, a grinding component and a nozzle adjustment component;

[0031] The workbench 1 is provided with a first notch 31, and a second bracket 21 is fixedly connected below the workbench 1 for fixing the second motor 20. A water tank bracket 22 is fixedly connected below the workbench 1 on one side of the second bracket 21, and a water tank 23 is fixedly connected to the water tank bracket 22. A water pump 24 is fixedly installed on the water tank 23, which can control the water in the water tank 23 to spray outward. A water pipe 25 is connected to the water tank 23, and a telescopic hose 32 is connected to the end of the water pipe 25 away from the water tank 23, so that the frame 18 can drive the water spray pipe 36 and the nozzle 37 to move up and down. The end of the telescopic hose 32 away from the water pipe 25 is connected to the water spray pipe 36. A support frame 2 is provided above the first notch 31, and two second notches 11 are provided on the workbench 1, so that two sliders 29 can slide. A third notch 12 is provided between the two second notches 11, so that the clamping mechanism can drive the steel bars after cutting to move up and down, and a third bracket 14 is fixedly connected to the outside of the workbench 1. It is used to fix the third motor 13.

[0032] A length control mechanism for controlling the cutting length of the steel bar is provided below the support frame 2. The length control mechanism includes a first telescopic rod 4, a wheel frame 5, a first roller 6, a second roller 26, and a servo motor 30. The first telescopic rod 4 is fixedly connected to the bottom of the support frame 2, and the output end of the first telescopic rod 4 is fixedly connected to the wheel frame 5, so that the wheel frame 5 can be controlled to move up and down, so that the first roller 6 can clamp the steel bar with the second roller 26 according to the thickness of the steel bar. The first roller 6 is rotatably connected to the wheel frame 5 to ensure that the steel bar can slide forward normally. The servo motor 30 is fixedly installed in the first notch 31, and the transmission shaft of the servo motor 30 is fixedly connected to the second roller 26. The servo motor 30 drives the second roller 26 to rotate. According to how long it takes for the second roller 26 to rotate one circle and how many meters the steel bar has advanced, how long it takes to rotate the corresponding number of meters is calculated, and finally the servo motor 30 is used to control the rotation time, so that the steel bar can be accurately cut according to the required steel bar length. The first roller 6 is aligned with the second roller 26 up and down to ensure that the steel bar can be accurately clamped.

[0033] The workbench 1 is fixedly connected with a gantry 3, and a cutting mechanism is arranged inside the gantry 3. The cutting mechanism includes a first motor 16, a cutting blade 17, a frame plate 18, a first screw rod 33, a first slide rod 19, and a second motor 20. The first screw rod 33 is rotatably connected between the gantry 3 and the workbench 1, and the first slide rod 19 is fixedly connected between the gantry 3 and the workbench 1. The frame plate 18 is slidably connected to the first slide rod 19 and the first screw rod 33. When the first screw rod 33 rotates, the frame plate 18 can slide up and down on the first slide rod 19 and the first screw rod 33, so as to control the cutting blade 17 to cut steel bars of different thicknesses. The first motor 16 is fixedly installed On the frame plate 18, the cutting blade 17 is fixedly connected to the transmission shaft of the first motor 16. The first motor 16 controls the cutting blade 17 to rotate at a high speed, thereby cutting the steel bars. The cutting blade 17 and the grinding surface of the second grinding plate 15 are on the same horizontal plane. In this way, when the steel bar cutting is completed, the clamping structure drives the just cut steel bar downward, and its cutting surface can be directly ground. The second motor 20 is fixedly installed on the second bracket 21. The transmission shaft of the second motor 20 passes through the workbench 1 and is fixedly connected to one end of the first screw rod 33. The second motor 20 can control the rotation of the first screw rod 33, thereby realizing the frame plate 18 sliding up and down on the first screw rod 33.

[0034] The grinding assembly includes a second screw rod 27 and a first grinding plate 10. The second screw rod 27 is rotatably connected to the second slot 11. One end of the second screw rod 27 is fixedly connected to a third motor 13. The second screw rod 27 can be rotated by starting the third motor 13. The third motor 13 is fixedly mounted on the third bracket 14. A second slide bar 28 is provided on one side of the second screw rod 27 and is fixedly connected to the second slot 11. The second screw rod 27 and the second slide bar 28 are respectively slidably connected to a slider 29. When the second screw rod 27 rotates, the two sliders 29 can slide on the second screw rod 27 and the second slide bar 28 respectively. The two sliders 29 are fixedly connected to the third motor 13 below. The second grinding plate 15, when the two sliders 29 slide, can drive the second grinding plate 15 to slide together, the two sliders 29 are fixedly connected with a receiving frame 7, when the two sliders 29 slide, can drive the receiving frame 7 to move together, so that it can slide to the first grinding plate 10 according to the length of the cut steel bar, and then under the action of the cylinder 8, the previous cutting surface is polished, and the new cutting surface is also polished on the second grinding plate 15, the receiving frame 7 is fixedly installed with a cylinder 8, the output end of the cylinder 8 is fixedly connected with a landing gear 9, the cylinder 8 is used to push the landing gear 9 to rise and fall, and the first grinding plate 10 is fixedly connected to the inner wall of the workbench 1.

[0035] A clamping mechanism for clamping steel bars is provided inside the landing gear 9, and the clamping mechanism includes two second telescopic rods 38 and two clamping blocks 39. The two second telescopic rods 38 are respectively fixedly connected to the inner walls on both sides of the landing gear 9, and the output ends of the two second telescopic rods 38 are respectively fixedly connected with clamping blocks 39. The two second telescopic rods 38 drive the two clamping blocks 39 to move closer to each other, so that the steel bars can be clamped.

[0036] The nozzle adjustment assembly includes a rack plate 34, which is fixedly connected to the gantry 3. A gear 35 is provided on one side of the gantry 3. The gear 35 is meshed with the rack plate 34, so that when the gear 35 slides up and down, the gear 35 can be rotated under the action of the rack plate 34. A nozzle 37 is fixedly connected to the gear 35, and the nozzle 37 is rotatably connected to the water spray pipe 36. The water spray pipe 36 is fixedly welded under the frame plate 18. In this way, when the frame plate 18 is lifted and lowered, the nozzle 37 on the water spray pipe 36 can be adjusted in angle under the action of the gear 35, thereby expanding the coverage of the water flow sprayed by the nozzle 37. In this way, when the steel bar is thicker, the cutting depth of the cutting blade 17 is increased, and the cutting blade 17 can be sprayed with water for cooling over a large range without increasing the water flow, thereby avoiding the waste of water resources.

[0037] When using the device, first place the steel bar to be cut on the second roller 26, and start the first telescopic rod 4 according to the thickness of the steel bar. The first telescopic rod 4 drives the first roller 6 to press the steel bar downward, and start the servo motor 30 to drive the second roller 26 to rotate, so as to drive the steel bar so that the cut part enters under the cutting blade 17. According to how long it takes for the second roller 26 to rotate one circle and how many meters the steel bar advances, it is calculated how long it takes to rotate for the corresponding number of meters. Finally, the servo motor 30 controls the rotation time, so that the steel bar can be accurately cut according to the required steel bar length. When the cut part of the steel bar reaches under the cutting blade 17, the two second telescopic rods 38 are started. The output ends of the two second telescopic rods 38 are respectively fixedly connected with clamping blocks 39, and the two second telescopic rods 38 drive the two clamping blocks 39 to move closer to each other to clamp the steel bar, and then the first motor 16 is started to drive the cutting blade 17 to rotate at a high speed, and the second motor 20 is started to drive the first screw rod 33 to rotate, so that the frame plate 18 slides downward along the first screw rod 33 and the first sliding rod 19. At the same time, the water spray pipe 36 on the frame plate 18 drives the nozzle 37 to descend. During the descent process, the gear 35 on the nozzle 37 drives the nozzle 37 to rotate and adjust the angle under the action of the rack plate 34, so that the nozzle 37 is aligned with the cutting blade 17 and the cutting position of the steel bar. When cutting the steel bar, the water pump 24 is started to work, so that the water in the water tank 23 enters the telescopic hose 32 through the water pipe 25 and is sprayed out from the nozzle 37 on the water spray pipe 36, so as to cool the cutting blade 17 and the steel bar. When the cutting is completed, the first screw rod 33 is controlled to drive the frame plate 18 to slide upward, so that the frame plate 18 drives the water spray pipe 36 to rise, and the water spray pipe 40 drives the nozzle 37 to rise. During the rising process, the gear 35 on the nozzle 37 drives the nozzle 37 to rotate and adjust the angle under the action of the rack plate 34, thereby expanding the coverage of the water flow sprayed by the nozzle 37, so that the cutting blade 17 can be sprayed with water over a large range without increasing the water flow. Cooling down avoids the waste of water resources, and then controls the third motor 13 to rotate the second screw rod 27, so that the slider 29 drives the second grinding plate 15 and the receiving frame 7 to slide, so that the clamping mechanism in the landing gear 9 will drive the cut steel bar to slide, and when one end of the steel bar hits the first grinding plate 10, the third motor 13 is stopped, and the cylinder 8 is started to drive the landing gear to descend to a certain position, and then the cylinder 8 is controlled to drive the landing gear 9 to slide up and down, so that the new cutting surface is polished on the second grinding plate 15. If the steel bar is cut for the second time, the previous cutting surface is polished on the first grinding plate 10, so as to avoid the situation that the cutting surface of the steel bar is not flat and has burrs after cutting.
